Plastic spur gears with a steel core, module 3, 44 teeth, and a 70 mm outer diameter, featuring a 20 mm bore and 30 mm face width. The gear is made of MC602ST nylon fused to an S45C steel core using a diamond-knurled surface process for high holding strength. It meets JIS grade N9 (JIS B1702-1: 1998) and has a 20° pressure angle with standard full-depth teeth. The allowable torque is 54.0 N·m (5.51 kgf·m), with a theoretical backlash of 0~0.56 mm. The total length is 95 mm. Dimensional stability and performance are maintained across wide temperature ranges, with examples of use up to 140°C.
